Gumroad Video Scraper 作者： Dan

Opens first found jwplayer or youtube embed in another tab on gumroad.com. Hit the button to run.

Made this becuase gumroad.com does not have a very good implementation of video players, preventing users from changing volume, skipping ahead, etc.

The extension is not very aesthetically pleasing as it just adds a button onto the page, but if someone would like me to, I'd be happy to clean it up a little.
